I just tried the Acoustic Java near Rotman's and recommend it.

I also love New Tradition. I think it's on Jackson Street in the Main South area.

iKrave on Park Ave doesn't get enough recognition. It's good for more of a donut shop style coffee and iced coffee. They have some great muffins and other baked good, too. Definitely not that hipster vibe you get at the first two places but it's been my go to for a quick morning coffee before work.
